In the late 80s, I made it to sandan in Shotokan. Not long after that, my instructor quit because of politics, and in solidarity, I did the same. Now, at 71, I continue to train but attaining higher ranks has lost its value because of the politics involved. I have no regrets. As an instructor, I see that lack of discipline, dedication, and motivation as the main reason students rarely attain shodan level. It ain't easy, folks! Otherwise, everyone would have a black belt. (I'm typing this at the 0:54 mark)

No belts in my system 🥲 but goals are always great. Currently working on my side splits

At least in aikido, it's really all political after 3rd degree black belt. You start a school and every 3-5 years, you get a higher rank.

High ranks indicate your teaching ability not your skill level C.c Rhee who could of been a grandmadter 30 years ago use to tell us that he wasn't an over grader At 35 your fitness level has peaked .Not all but often I have seen high level senior masters and grandmasters who are fat and slow and an embarrassment who just keep getting charity Dan grades to beat their chests their hopeless.👍👍
